Heat Recovery from Rotary Kilns - Low grade heat capture for the cement industry
A heat recovery system that captures heat lost from rotary kiln surfaces in cement, paper and sponge iron plants and putting it to useful work.
The outside surface temperature of the kiln ranges from 200-300°C. The solution captures the heat lost to ambient during raw material calcination which takes place at 1200°C. The concept utilizes heat recovery panels placed parallel to the kiln. The heat recovery panels are made of aluminium with copper pipes embedded in them. As the panel temperature is lower than the kiln surface temperature, the heat radiated by the kiln surface is captured by the panels and finally transferred to the heat transfer fluid circulating in the copper pipes. The heat captures using this solution are low grade heat between 90-110°C.
